INTRODUCTION Basic instructions Technical
Information This manual has been produced by a
new technical information system. This new system
is designed to deliver technical information
electronically through CDROM and in paper
manuals. A coding system called ICE has been
developed to link the technical information to
other Product Support functions e.g.
Warranty. Technical information is written to
support the maintenance and service of the
functions or systems on a customers machine.
When a customer has a concern on his machine it
is usually because a function or system on his
machine is not working at all, is not working
ef?ciently, or is not responding correctly to his
commands. When you refer to the technical
information in this manual to resolve that
customers concern, you will ?nd all the
information classi?ed using the new ICE coding,
according to the functions or systems on that
machine. Once you have located the technical
information for that function or system then you
will ?nd all the mechanical, electrical or
hydraulic devices, compo- nents, assemblies and
sub-assemblies for that function or system. You
will also ?nd all the types of information that
have been written for that function or system,
the technical data (speci?cations), the
functional data (how it works), the diagnostic
data (fault codes and troubleshooting) and the
service data (remove, install adjust, etc.). By
integrating this new ICE coding into technical
information , you will be able to search and
retrieve just the right piece of technical
information you need to resolve that customers
concern on his machine. This is made possible by
attaching 3 categories to each piece of technical
information during the authoring process. The
?rst category is the Location, the second
category is the Information Type and the third
category is the Product
LOCATION - is the component or function on the
machine, that the piece of technical information
is going to describe e.g. Fuel tank. INFORMATION
TYPE - is the piece of technical information that
has been written for a particular component or
function on the machine e.g. Capacity would be a
type of Technical Data that would describe the
amount of fuel held by the Fuel tank. PRODUCT -
is the model that the piece of technical
information is written for.



Every piece of technical information will have
those 3 categories attached to it. You will be
able to use any combination of those categories
to ?nd the right piece of technical information
you need to resolve that customers concern on his
machine. That information could be
the description of how to remove the cylinder
head a table of speci?cations for a hydraulic
pump a fault code a troubleshooting table a
special tool

How to Use this Manual This manual is divided
into Sections. Each Section is then divided into
Chapters. Contents pages are included at the
beginning of the manual, then inside every
Section and inside every Chapter. An alphabetical
Index is included at the end of a Chapter. Page
number references are included for every piece of
technical information listed in the Chapter
Contents or Chapter Index. Each Chapter is
divided into four Information types
(D) Technical Data (speci?cations) for all the
mechanical, electrical or hydraulic devices,
components and, as- semblies. (C) Functional
Data (how it works) for all the mechanical,
electrical or hydraulic devices, components and
as- semblies. (G) Diagnostic Data (fault codes,
electrical and hydraulic troubleshooting) for all
the mechanical, electrical or hydraulic devices,
components and assemblies.

1. Park the machine on a level surface. Lower the
   loader bucket to the ?oor. Stop the engine.
2. Disconnect the hose from the ?tting on the
   pressure port (1) of the hydraulic pump. Install
   a T ?tting at the pressure port (1) on the
   hydraulic pump. Reconnect the pressure hose to
   one side of the T ?tting. Con- nect the ?owmeter
   inlet hose to the remaining con- nection on the
   T ?tting. Place the ?owmeter outlet hose into
   the reservoir. Secure the outlet hose to the
   reservoir so that the hose is submerged below the
   surface of the hydraulic oil.

1. Make sure that the oil level in the hydraulic
   reservoir is correct.
2. The oil must be at operating temperature. If the
   oil is not at operating temperature, run the
   engine at full throttle. Hold the auxiliary
   hydraulic ?ow control pedal in the ON position
   and close the pressure valve of the ?owmeter
   until the pressure gauge indicates 103 bar (1500
   psi). Continue to run the engine at full
   throttle until the temperature of the oil is 52C
   (125F).
3. Continue to hold the auxiliary hydraulic ?ow
   control pedal in the ON position. Continue to
   run the engine at full throttle. Slowly close
   the pressure valve. As the pressure increases,
   the ?ow indication will de- crease slowly. As
   you continue to close the pressure valve, you
   will reach a point at which the ?ow indica- tion
   begins to decrease rapidly. This is the point at
   which the main relief valve starts to open. Read
   the pressure gauge and record the reading as
   test num- ber 5.
4. Continue to close the pressure valve until the
   indi- cation of the ?ow gauge is zero. This is
   the point at which the main relief valve is
   completely open. Read the pressure gauge and
   record the reading as test number 6.
5. Open the pressure valve completely. Decrease the
   engine speed to low idle and stop the engine.
6. Refer to speci?cations Relief valve - General
   spec- i?cation (A.10.A) Relief valve - General
   speci?ca- tion (A.10.A) If the pressure setting
   of the main re- lief valve is not within the
   speci?cations, you must replace the main relief
   valve.
7. If you replaced the main relief valve, repeat
   steps 5 through 7.

• If the completely open pressure (step 6) is as
  spec- i?ed, but the pressure at which the main
  relief valve begins to open (step 5) is 205 bar
  (2975 psi) or less, the main relief valve is
  damaged and must be re- placed before you do
  further testing.
• NOTE Understanding the results of the tests are
  outlined in the steps below.
• Refer to Hydraulic pump - Flow test (A.10.A) Hy-
  draulic pump - Flow test (A.10.A) If the ?ow
  indica- tion for a circuit was approximately the
  same as the ?ow indication at the same pressure
  in Test Number 1 of the Hydraulic Pump Flow Test
  , the circuit is good.
• If the ?ow indication for a circuit was more than
  3.8 L/min (one gpm) less than the ?ow indication
  at the same pressure in Hydraulic pump - Flow
  test (A.10.A) Test Number 1, there is leakage in
  that circuit.

• With the engine running at full throttle, hold
  the bucket control lever in the ROLLBACK
  position for 10 seconds.
• Put the bucket control lever in the NEUTRAL po-
  sition for 10 seconds.
• Repeat steps A and B until the temperature of the
  oil is 52 C (125 F) or the side of the
  reservoir is very warm.
• Use a pressure gauge with a capacity of at least
  276 bar (4000 psi). Connect the pressure gauge
  to one of the auxiliary hydraulic couplers on
  the left hand loader arm.
• Run the engine at full throttle. Actuate the
  auxil- iary hydraulic ?ow control pedal to
  pressurize the hy- draulic line which has the
  pressure gauge. Record the indication on the
  pressure gauge. Then return the auxiliary
  hydraulic ?ow control pedal to the Neu- tral
  position and decrease the engine speed to low
  idle. Stop the engine.
• Compare the indication with the speci?cation .

1. If the output at minimum pressure was less than
   the speci?cation for Gear Pump Flow to Loader
   (Ma- chine in Neutral) refer to Hydraulic pump -
   General speci?cation (A.10.A), the problem can
   be a restric- tion between the reservoir and the
   gear pump, or the problem can be a badly worn or
   damaged gear pump.
2. If the output at minimum pressure was more than
   the speci?cation refer to Hydraulic pump -
   General speci?cation (A.10.A), there are no
   problems be- tween the reservoir and the gear
   pump. However, the gear pump can be worn or
   damaged and still have good ?ow at minimum
   pressure.
3. Loss of output at 152 bar (2200 psi) indicates
   that the gear pump is worn or damaged. To
   determine the ef?ciency of the gear pump, divide
   the ?ow indi- cation from test number 4 by the
   ?ow indication from test number 1. This answer
   multiplied by 100 is the percent ef?ciency of
   the gear pump. If the ef?ciency of the gear pump
   is less than 75, repair or replace the gear
   pump. If the ef?ciency of the gear pump is more
   than 75, the pump is good.
